When to Open Packs?

All my good pulls in packs come right after winning a game( especially right after completing daily challenges)  and i definitely get absolute crap after having been in the menus for a long time, especially when the menu starts to lag because of their crap coding.

Also, I never open a pack when it is first presented to you, I always back it out and open any pack from unopened packs. 

I mainly brought this up bc i saw JonBeast get 0-50 on his snow packs and i feel like he wasn't in the pack slipstream, so to speak

Ik this is mainly superstition, but does anyone have any small tips for opening packs that they follow?
